Separating Flows

A basic theoretical analysis of the interaction of a transonic normal shock wave with a non-separating turbulent boundary layer in a background pressure gradient is given. The method is based on an extension of Inger and Mason’s small disturbance analysis to account for both explicit pressure gradients upstream and downstream of the interaction and the implicit pressure gradient effects on the local boundary layer shape plus the back-effect of the interaction-induced boundary layer thickness growth (blockage) that is important in channel flows and turbomachinery applications. The theory predicts the detailed disturbance pressure and skin friction distributions, including lateral pressure gradients, and is readily imbedded locally in a global calculation scheme involving transonic inviscid and boundary layer prediction codes upstream and downstream of the shock. Good agreement is found between the resulting theoretical predictions and experimental results for non-separating flows.
